Best way to obtain CAPM Certification for a group of six

Hello,

I am part of a large organization.  We have six new hires, including myself, that are looking to get our CAPM certifications.  We are all basically fresh out of college, in an early career development program.  Our program manager has instructed us to research training requirements and other options that we have in order to obtain the CAPM  Certification.  What would be the most cost and time effective way to do this.  

We have been looking at PMI's website for training options.  The group would prefer instructor led seminar courses, however, the only instructor courses that we have been able to find that were not webinars were PMP/CAPM courses.  I think most of the R.E.P.s (Registered Education Providers) only provide PMP courses, and they just tack on CAPM in order to get a slightly larger group.  But if we were to take these courses, we would have to intake a lot of PMP information that would not be related to the CAPM exam, so it would be information overload.

Do you guys know of any sole CAPM courses?  Would you recommend another alternative?  Our program champion is willing to invest in this, so although we are on a budget, I believe we can afford to spend some money on this.

Thanks!
